TMI-when do nipples stop being sexually sensitive? 😖

I'm 37 weeks and fully intend to b/f but although my nipples are sore and will leak when stimulated, I'm still getting the kinds of feelings 'down there' that I definitely DO NOT want to get once the baby is born. When does the sexual tingling go away? I'm worried it won't since I'm full term and still have it 😕
